We run PHP 7.4 on our server, but not yet on X-Cart, for obvious reasons.

It would be beneficial for ALL, if, the very next upgrade of XC 5.4.0.7 aka #TheBugKiller fully supported PHP 7.4.

Why? Well surely XC would prefer all of their customers to switch over to the XC 5.4.* series anyway? So why not apply some quality technical engineering test time** and give all your customers an added incentive to make the switch? Makes perfect common and commercial sense to us

**As opposed to wasting even more time on endless, dreary, poorly worded, html marketing drivel that's provided by the "...storyteller at X-Cart" (sic)

"...the XC code itself" Being blunt, this should be the easiest and quickest to do and should have been on the project road map over a year ago (if the job was being done correctly).

3rd party packages Not usually XC's finest hour as you know even better than we do. XC frequently, simply leave these alone and allow the XC Core to utilise outdated, old releases. Again, all these should have been on the project road map and somebody, somewhere in XC, should have (and should be now) already aware of if / what / their PHP 7.4 supporting status is etc (if the job was being done correctly)

Harsh? Only fair we think in today's quick response world of software providers

Edit @mvs has since provided the somewhat predictable XC official response Ah well
